OpenGov, the firm co-founded by Palantir’s Joe Lonsdale that helps government and other civic organizations organise, analyse and present financial and other data using cloud-based architecture, has raised another big round of funding to continue expanding its business. The startup has picked up an additional $51 million in a Series D round led by Weatherford Capital and 8VC (Lonsdale’s investment firm), with participation from existing investor Andreessen Horowitz.
